That means that if clubs are looking to sign non-Russian NHL players, they must have played in either 150 NHL games, on national teams, in the KHL previously or won a Stanley Cup or individual trophy.

The rules will go into effect the day the NHL announces the lockout and be enforced until the situation is resolved. Owners maintain that they'll lock out the NHLPA on Sept. 15.

"Our clubs are getting an opportunity to enter into contracts and to put on their rosters no more than three NHL players, and these players can be included above the established limit of 25 players," vice president Vladimir Shalaev said, according to a translation by Yahoo! Sports.

"Of the three NHL players signed to a contract by Russian KHL clubs, there may be only one (foreign-born) player. And it cannot be just any foreign born player, but one who meets one of the special criteria that was set in place to ensure only top level players come to the KHL."

Lockout-only rentals will not be counted towards the KHL salary cap, according to Yahoo!, but they can't be paid more than 65 percent their NHL salaries.

Alex Ovechkin and Evgeni Malkin have both said that they'll play in their home country during the lockout, though they wouldn't be subject to the new guidelines. Sidney Crosby, who said Tuesday that he's considering playing in Europe, would pass muster.
